lNVALlD BEDST-EAD.

SPEGIFIGATION forming part of Letters Patent No. 718,746, dated January 20, 1903. Application filed January 23, 1902. Serial No. 90,926. (No model.)

To otZZ whom it may concern:

Be it known that I, SILAs W. BENNETT, a citizen of the United States, residing at Mc- Donald, in the county of Washington and State of Pennsylvania, have invented certain new and usefulImprovements in Invalid-Bedsteads; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to invalid-bedsteads.

The object of the invention is to provide a bedstead of this character which shall be simple of construction, durable in use, comparatively inexpensive of production, and which may be easily and expeditiously operated.

With this and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved bedstead, showing the head-section of the mattress adjusted. Fig. 2 is a top plan View with the mattress and springs removed. Fig. 3 is a longitudinal sectional view when the parts are in the position shown in Fig. 1, the headsection of the bed-frame and the foot-section being adjusted to expose for use the bed-pan. Fig.4 is a vertical cross-section al view through the intermediate mattress-sections, illustrating one of the parts of the said mattresssection adjusted; and Fig. 5 is a longitudinal sectional view through the bed-pan.

Referring to the drawings, 1 denotes the head-section of the bed-frame, and 2 the footsection. Each section is provided with four legs, in the ends of which are secured casters. The sections are connected together similar to the well-known form of extension-table that is, one section is provided on its under side with extension-bars 5, fixed thereto and projecting into fixed guides 6, secured to the under side of the other section, whereby the sections may be pulled apart and maintained in true parallelism or alinement. One section of the bedstead, preferably the section 1, has a shelf 7, which covers the space formed by the separation of the sections and is adapted to support a bed-pan 8, the construction of which will be hereinafter specifically set forth.

9 denotes sets of springs, and 10 denotes the mattress supported by said springs. The mattress consists of five piecesnarnely, the footsection 11, the intermediate section 12, which is composed of three parts a, b, and c, and the head-section 13. The parts a and c of the intermediate section are hinged at their inner edges to the part Z) and are capable of being swung upward, as shown in Fig. 4, to roll or move the patient from one side of the bed to the other. The sections 11 and 13 are not connected to the section 12 and are therefore independent of said section 12.

14 denotes a rock-shaft journaled in the head-section and provided with lifting-arms 15, arranged within the spaces between the springs. This shaft is provided with a segmental gear 15, which is engaged by a pinion 16, having a crank 17 for rotating it. By rotating this pinion the section 13 of the mattress may be elevated to any desired angle.

18 denotes a transversely-arranged rockshaft, having at one end a lifting-crank 19, arranged under the part c of the mattress and provided at its opposite end with a turning-crank 20, by means of which the shaft may be rocked to elevate the part c of the mattress. 21 denotes a similar shaft similarly mounted and provided with a crank-arm 22, located under the section a of the mattress. This shaft is also provided with aturningcrank 23, whereby the shaft may be rotated for inclining the section a of the mattress.

24 and 25 denote links, the link 24 being pivoted to the section 1 of the bed-frame and the link 25 being pivoted to the section 2 of the bed-frame. These links are pivotally connected to a lever 26, which enables the sections 1 and 2 of the bed-frame to be moved apart or toward each other.

The bed-pan 8, hereinbefore referred to, has a cover formed of two sections 27, hinged to the pan and provided with springs 28, which tend to hold them open. A link 29 is pivotally connected at one end to one of said covers and is pivotally connected at the other end to a projection extending .below the hinged end of the cover, whereby when one hinged section is depressed the other will likewise be depressed and when one opens the other will likewise open. The bed-pan 8 is supported upon the shelf 7 under the mattress-section 11, whereby when the lever 26 is operated to spread the sections 1 and 2 of the bed-frame apart the mattress-section 11 will be withdrawn from over the bed-pan, and the cover sections of said pan will, through the energy of their springs, swing upwardly against the inner ends of the part b of the mattress and the mattress-section 11, as more clearly shown in Fig. 3, thus preventing said mattress-sections from being soiled.

\Vhen the sections 1 and 2 of the bed-frame are brought together, the mattress will close that section of the bed-pan cover against which it abuts, and the movement of this section of the cover will close the other section of the cover, so that the pan will be entirely closed and in this position may be withdrawn from the side from under the mattress.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood without requiring an extended explanation.

Various changes in the form,proportion,and details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described myiuvention, what I claim, and desire to secure by Letters Patent, is

1. The combination with a bed-frame consisting of extensible sections, a shelf carried at the inner end of one section and adapted to bridge the space formed by the separation of the two sections in the act of extending the same and support a bed-pan, of independent mattress-sections upon said extensible sections, whereby upon the extension of the bed-frame sections and the separation of the mattress-sections the bed-pan will be exposed for use, substantially as set forth.

2. The combination with a bed-frame consisting of extensible sections, and independent mattress-sections supported upon said extensible sections, of a bed-pan located upon one of said bed-frame sections and adapted to be exposed for use upon the separation of the mattress-sections, due to the extension of the bed-frame sections, said bed-pan being provided with spring actuated coversections adapted to automatically open when the mattress-sections are separated, substantially as set forth.

3. The combination with a bed-frame consisting of extensible sections, and independent mattress-sections supported upon said extensible sections, of a bed-pan located upon one of said bed-frame sections and adapted to be exposed for use upon the separation of the mattress-sections, due to the extension of the bed-frame sections, said bed-pan being provided with spring-actuated cover-sections adapted to automatically open when the mattress-sections are separated, said cover-sections being connected by a pivoted link whereby upon the movement of said mattress-sections toward each other, said cover-sections will be closed, substantially as set forth.

4. The combination with bed-frame sections having extensible connections, of links, one pivoted to one of the bed-frame sections and the other to the other bed-frame section, and a lever pivoted to the inner ends of said links, whereby said bed-frame sections may be extended or retracted, substantially as set forth.

5. The combination with a bed-frame, of independent mattress-sections 11, 12 and 13, the section 12 being composed of three parts, lying side by side parallel with the length of the bed-frame, the outer parts being hinged to the inner part, and means for adjusting the section 13, substantially as set forth.

(3. The combination with a bed-frame, of three independent mattress-sections, the intermediate one of which is composed of three parts lying side by side parallel with the length of the bed-frame, the outer parts being hinged to the middle part, and means for inclining either outer part, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

SILAS W. BENNETT.
